Holy shit. I looked it up if there's a released ch15 on another website but instead found out that there's a novel about this?! Omfg
Both are part of novel series taking place in the same universe. The author (Zig) writes novels and works together with different artists for manhwa adaptions, that's the reason why the art of KML and KMIYC looks a bit different.
You won't find chapter 15 in the near future, because the artist is on a longer hiatus right now. The novel itself was completed for a few year ago, problem is that the official english translation is still not completed.-_-
At the moment the author is releasing "Desire me if you can" in korean as a webnovel, the story also takes place in the same universe. It's Grayson's story, and since his pair is Dane ( he is 196cm tall, by the way...)...there is also a lot of fighting and hitting so far. What I found extremely funny is in one of the latest chapters Dane lamented that Grayson is his karma.XD So far it is really entertaining, because Grayson is hillarious ( you'll be really surprised what difference it makes reading his pov and following that guy around, most hated him after reading KMIYC novel), Dane is often too naive when it comes to Grayson, and they are both clueless idiots.^^
To be honest, I didn't really like Kiss Me, Liar that much and avoided the author's other works but I stumbled blindly on this one not knowing they're the same author but the art was just familiar. Really loved Josh's character not taking any shit from Chase lmaoo really can't wait for chapter 15
